The time’s finally arrived, Sony Ericsson have officially announced the Android powered Xperia handset. We first heard of the handset under the codename of Rachael, which later became known as the X3. Rumours had started flying that the handset had been renamed to the X10 and with the announcement from Sony Ericsson, we can confirm this is correct.

Along with using Android as the operating system, it will also use a unique Sony Ericsson UX platform on top of the Android OS. The X10 will be the flagship phone of 2010 with release slated for the first half.

The X10 will be released in selected markets in Q1 in white or black. You can view the press release here and the X10 page here.

It may have only been a few days since the Xperia X2 was officially announced, but the handset is already available to pre-order. Rumors are going around that the handset will be released November 2nd in Italy for 600 Euros, but as of yet, I’m yet to see any sites confirming this.

In the UK however it’s a different story. Retailer Expansys, who previously listed the X3 for a couple of days, has the Xperia X2 listed for pre-order with a release date and price. It lists the specs which we already know, such as featuring an 8.1 megapixel camera, Windows Mobile 6.5 and TV Out. Expansys are listing the X2 with an estimated release date of 11 January 2010. The price of the handset is listed as £604.99.

This week Sony Ericsson have officially announced the release of the Xperia X2 along with the handset which was previously known as Kiki. The Xperia X2 is the successor to the popular Windows Mobile Xperia X1. The X2 will also run Windows Mobile but the updated 6.5 version. Engadget were also able to preview the Xperia X2, which at the moment, Windows Mobile 6.5 isn’t finalised, so there’s a bit of lag in the UI. The Xperia X2 also features an upgraded camera coming it at 8.1 mega pixels. Release date is set for Q4 of 2009, so hopefully we should see the handset before Christmas. You can view the video by Engadget after the jump.

The other Xperia handset announced, is not the Xperia Rachael, aka X3, but rather the handset we formally knew as Kiki. The handset, well known specs are limited at the moment, we have known it will feature a “transparent screen”. Again we have a video showing this which you can view after the jump. The display is visible from both sides of the handset, but if it only displays during certain screens or can be turned off is currently unknown. Hopefully it can be turned off, or not on during certain screens, other wise text messages soon won’t be very private. The handset has been named Xperia Pureness and is due for release also in Q4, with November as the month the coming is aiming for.

Both handsets will launch in selected markets during Q4. No price is known as of yet.

The mysterious handset from Sony Ericsson, Kiki, has passed through some of the net world as an unknown, strange, Sony Ericsson handset. Upon closer inspection, the handset bears the Xperia wording. Unlike the previous Xperia handsets though, it appears to lack the touch screen keyboard and takes on a transparent screen instead. While any specs of the handset are still undiscovered, some more photos of Kiki have surfaced.

We’ve seen the initial photos of the Xperia X3, we’ve seen some great photos of the handset in white. We’ve now got the stunning pictures of the handset in black, in much better quality than the original photos of Rachael.
